Cyclone separation device according to the present invention has such advantage: when device is used as wholely when considering, compare with the independent separative efficiency of independent rotational flow separation unit, it has higher separative efficiency.The existence of at least three series connection rotational flow separation unit has promoted the performance of system, thereby the variations in flow that appears at downstream units almost seldom or not can influence the ability that this unit keeps its separative efficiency.Therefore, compare with known cyclone separation device, separative efficiency is more stable.
It should be understood that we refer to the rotational flow separation unit is separated entrained particulates from air-flow ability by term " separative efficiency ", in order to compare, relevant rotational flow separation unit receives identical air-flow.Therefore, have the separative efficiency higher than second separative element in order to make the first rotational flow separation unit, when the two is in equivalent environment following time, first separative element must can be from the more a high proportion of particulate of carrying secretly of flow separation than second separative element.The factor that can influence the separative efficiency of rotational flow separation unit comprise the angle of size, tapering of inlet and outlet and cyclone length, cyclone diameter and be positioned at the length of the tubular intake section of cyclone upper end.
The size of the cyclone that makes that each is independent of accelerating of cyclone reduces along airflow direction in each continuous separative element.The fact of the air-flow by a plurality of upstream cyclone means that oarse-grained dirt and dust are removed, and this makes each little cyclone to turn round expeditiously and does not have the risk of obstruction.
Preferably, the first rotational flow separation unit comprises the first independent cyclone, more preferably, this first cyclone or each first cyclone are roughly cylindrical. and such structure makes that oarse-grained dust and chip can be collected reliably and store, and has the relatively low risk of carrying secretly once more simultaneously.

Be about to the cyclone separation device 100 of description below the present invention only relates to, therefore, right and wrong are substantial comparatively speaking for all the other features of vacuum cleaner 10,20.
Form each vacuum cleaner 10,20 the part cyclone separation device 100 as shown in Figure 3 and Figure 4. the specific general shape of cyclone separation device can change according to the type with the vacuum cleaner of auto levelizer 100 wherein. for example, between this device, the overall length of this device can increase or reduce, perhaps, the shape of bottom can change so that become for example frusto-conical.
Fig. 3 and cyclone separation device 100 shown in Figure 4 comprise outer bin 102, and this outer bin has and is roughly columniform outer wall 104.The lower end of outer bin 102 is sealed by bottom 106, and the mode of this bottom 106 by pivot 108 is pivotably mounted on the outer wall and is fixed on the position of closing (as shown in Figure 3) by knocker (catch) 110.On the closed position, the bottom is pressed on the lower end of outer wall 104 and is closed.When for the following illustrative purposes that is about to, make bottom 106 pivot when unclamping knocker 110 and leave outer wall 104.Second cylindrical wall 112 is positioned at the inside and with it separately of outer wall 104 diametrically, thereby forms annular chamber 114 between the two.This second cylindrical wall 112 join with bottom 106 (when the bottom in the closed position) and bear against sealing.Annular chamber 114 is defined by outer wall 104, second cylindrical outer wall 112, bottom 106 and the upper wall 116 that is positioned at the upper end of outer bin 102 generally.
Dust-loaded air intake 118 is positioned at the upper end of outer bin 102 and is lower than upper wall 116.Dust-loaded air intake 118 is set up with outer bin 102 tangent (see figure 4)s and is forced to advance along helical path around annular chamber 114 with the dust-loaded air of guaranteeing to enter.Fluid issuing is arranged in outer bin 102 with the form of sleeve pipe 120 (shroud).This sleeve pipe 120 comprises cylindrical wall 122, in this cylindrical wall, is formed with a large amount of perforation 124.Only fluid issuing that comes from outer bin 102 is formed by the perforation in sleeve pipe 124.Passage 126 is formed between the sleeve pipe 120 and second cylindrical wall 112, and this passage 126 is communicated with annular chamber 128.
Annular chamber 128 radially outwards is arranged in the upper end of swirl cone 130, and this cyclone is positioned at the position coaxial with outer bin 102.Cyclone 130 has and is roughly 132, two air intakes 134 of columniform upper entrance part and is formed in this cyclone.Inlet 134 is arranged around the circle spacing ground of upper entrance 132.Inlet 134 is the shape of slot-like and directly is communicated with annular chamber 128.Cyclone 130 has the tapering part 136 that dangles from upper entrance 132.This tapering part 136 is a conical butt, and ends in cone opening 138 in its lower end.
One on the outer wall section of the tapering part 136 of bottom 106 and cyclone 130 of three cylindrical shape wall portion 140 extends between the part above the cone opening 138.When bottom 106 was in the position of closing, three cylindrical shape wall portion 140 was born against sealing.Therefore, cone opening 138 is opened the circular cylindrical cavity 142 that specifically seals to.Vortex finder (vortexfinder) 144 is positioned at the upper end of cyclone 130 and leaves cyclone 130 to allow air.
Vortex finder 144 is communicated with the pressure stabilizing cavity that is positioned at cyclone 130 tops (plenumchamber) 146.Is a plurality of cyclones of arranging 148 around pressure stabilizing cavity 146 along circumferential arrangement parallel with one anotherly.Each cyclone 148 has the tangential inlet 150 that is communicated with pressure stabilizing cavity 146.Each cyclone 148 identical with other cyclone 148 and comprise cylindrical upper section 152 and by its dangle and under tapering part 154.The tapering part 154 of each cyclone 148 stretches into annular chamber 156 and is communicated with it, and this annular chamber is between second cylindrical wall 112 and three cylindrical shape wall portion 140.The upper end of each cyclone 148 has a vortex finder 158, and each vortex finder 158 is communicated with outlet plenum 160, and this outlet plenum has and is used for clean air is transferred out outlet 162 outside the device 100.
As mentioned above, cyclone 130 is coaxial with outer bin 102.It is the annulus at center that eight cyclones 148 are arranged in an axis 164 with outer bin 102.Each cyclone 148 has the axis 166 that is tilted to down and levels off to axis 164.Each axis 166 tilts with identical angle with respect to axis 164.In addition, the bevel angle of cyclone 130 is greater than the bevel angle of cyclone 148, and the diameter of the upper entrance part 132 of cyclone 130 is greater than the diameter of the cylindrical upper section 152 of each cyclone 148.
In the use, the air that is loaded with dust is by dust-loaded air intake 118 accesss to plant 100, and because the tangential tectonics of inlet 118, described air-flow advances along helical path around outer wall 104. big dirt and dust granule by cyclonic action in annular chamber 114 deposition and being collected in wherein. the air communication that was partly cleaned is crossed the perforation 124 that is arranged in sleeve pipe 122 and is left annular chamber 114 also after the admission passage 126., this air-flow enters annular chamber 128 and carries out in the inside of cyclone 130 from inlet 134. rotational flow separation of this arrival cyclone 130, thereby some dirt that still is entrained in the air-flow being separated with dust. dirt that is gone out from flow separation in cyclone 130 and dust deposit are circular cylindrical cavity 142, simultaneously, the air communication that is further cleansed is crossed vortex finder 144 and is left after the cyclone 130., this air-flow enters pressure stabilizing cavity 146 and enters in one of eight cyclones 148 from this, therein, further rotational flow separation is removed some dirt still carried secretly and dust. and described dirt and dust deposit are in annular chamber 156, the air that cleaned simultaneously leaves cyclone 148 by vortex finder 158 and goes forward side by side in the inlet/outlet chamber 160. and afterwards, the air that cleaned is by outlet 162 separating devices 100.
Dirt that is separated from air-flow and dust will be collected in three cavitys 114,142 and 156.In order to empty these cavitys, knocker 110 is released so that rotate around pivot 108 bottom 106, and therefore, this bottom falls to leaving the lower end of cylindrical wall 104,112 and 140.So, dirt and the dust that is collected in cavity 114,142 and 156 can be cleared up away from installing 100 easily.
Should recognize that from description before device 100 comprises three visibly different stages of cyclonic separation.Outer bin 102 constitutes the first rotational flow separation unit, and this rotational flow separation unit comprises and is roughly the columniform first independent cyclone.In this rotational flow separation unit, the major diameter comparatively speaking of outer wall 104 means that because it is relative less with the centrifugal force of chip to put on dirt, bigger dirt and detrital grain will at first be separated from air-flow.Some fine dust also can be separated.The overwhelming majority of big chip will be deposited in the annular chamber 114 reliably.
Cyclone 130 forms the second rotational flow separation unit.In this second rotational flow separation unit, the radius of second cyclone 130 is much smaller than the radius of outer wall 104, thus put on the remaining centrifugal force of carrying dirt and dust secretly will be much larger than putting on the dirt in the first rotational flow separation unit and the centrifugal force of dust.Therefore, the efficient of the second rotational flow separation unit is higher than the efficient of the first rotational flow separation unit.Because what face is the air-flow that has the less entrained particles of size range, and larger particles has been removed by the rotational flow separation of carrying out in first cyclone of first separative element, so therefore the performance of the second rotational flow separation unit also gets a promotion.
The 3rd rotational flow separation unit is formed by eight less cyclones 148.In this 3rd rotational flow separation unit, each the 3rd cyclone 148 has the diameter littler than second cyclone 130 of the second rotational flow separation unit, therefore can separate more tiny dirt and dust than the second rotational flow separation unit.The 3rd rotational flow separation unit also has the advantage of enclosing: what face is the air-flow that was cleaned by first and second rotational flow separation unit, thereby the quantity of entrained particles and big or small all less than respective numbers and size in other debatable situation.This has reduced inlet that makes cyclone 148 and any risk that exports obstruction.
Therefore, the separative efficiency of the first rotational flow separation unit is lower than the separative efficiency of the second rotational flow separation unit and the separative efficiency of the second rotational flow separation unit is lower than the separative efficiency of the 3rd rotational flow separation unit.At this, we refer to that first efficiency of hydrocyclone is lower than second efficiency of hydrocyclone and second efficiency of hydrocyclone is lower than all eight the 3rd separative efficiencies that cyclone is added up.Therefore, each efficiency of hydrocyclone increases progressively in order.
As mentioned above, cylindrical first cyclone, the 202. dust-loaded air intakes 218 that the first rotational flow separation unit comprises is independent, defined by outer cylindrical wall portion 204, bottom 206 and second cylindrical wall 212 are tangent with outer wall 204, to guarantee that rotational flow separation is carried out and the bulky grain of dirt and chip is collected in the annular chamber 214 in the lower end of cyclone 202 in first cyclone 202. as above, only passage of first cyclone 202 that is derived from is for entering the passage 226. between the sleeve pipe 222 and second cylindrical wall 212 by the perforation in the sleeve pipe 222 224
In this embodiment, the second rotational flow separation unit comprises second cyclone 230 of two tapers of arranging parallel with one anotherly.Second cyclone 230 is arranged side by side at the outer pars intramuralis of device 200, as shown in FIG. 6.Each second cyclone 230 has a upper entrance part 232, has at least one inlet 234 in this upper entrance part.Each inlet 234 is positioned for making tangential introduction of air to enter upper opening part 232 and is communicated with cavity 228, and this cavity 228 is communicated with passage 226.Each second cyclone 230 has the frusto-conical portion 236 of dangling from upper entrance part 232 and ends in cone opening 238.Second cyclone 230 protrudes in the closed housing 242.Each second cyclone 230 has the vortex finder 244 that is positioned at its upper end and is communicated with cavity 246.
The 3rd rotational flow separation unit comprises four the 3rd cyclones 248 of arranging in parallel.Each the 3rd cyclone 248 has a upper opening part 252, and this upper opening partly comprises an inlet 250 that is communicated with cavity 246.Each the 3rd cyclone 248 also has the frusto-conical portion 254 of dangling and being communicated with closed housing 256 by the cone opening from intake section 252.Cavity 256 with respect to cavity 242 by a pair of wall 270 (see figure 6)s closure.Each the 3rd cyclone 248 has the vortex finder 258 that is positioned at its upper end and is communicated with the outlet plenum 260 with outlet 262.
Each rotational flow separation unit all has than the higher separative efficiency in previous rotational flow separation unit.Because what face is wherein to be entrained with the air-flow of particle among a small circle, this makes that the running of the second and the 3rd rotational flow separation unit is more efficient.
Each rotational flow separation unit can comprise varying number and difform cyclone.But Fig. 7 to 9 schematically illustrates fall into the scope of the invention three kinds other arrangement.In these diagrams, except the quantity and general shape of the cyclone that forms each rotational flow separation unit, all details all will be left in the basket.
At first, in Fig. 7, device 300 comprises the first rotational flow separation unit 310, the second rotational flow separation unit 320 and 330. first rotational flow separation unit 310, the 3rd rotational flow separation unit comprise that independent cylindrical first cyclone 312. second rotational flow separation unit 320 comprise two conical butts of arranging in parallel, second cyclone 322 and the 3rd rotational flow separation unit 330 comprise eight be equally conical butt the 3rd cyclone 332. of arranging in parallel in this embodiment, the size of the 3rd cyclone 332 much smaller than the size of second cyclone 322 and the separative efficiency of the 3rd rotational flow separation unit 330 far above the separative efficiency of the second rotational flow separation unit 320.
